Airport passenger flow prediction using simulation data farming and machine learning

Passenger flow management is an important issue at many airports around the world. There are high concentrations of passengers arriving and leaving the airport in waves of large volumes in short periods, particularly in big hubs. This might cause congestion in some locations depending on the layout of the terminal building. With a combination of real airport data, as well as synthetic data obtained through an airport simulator, a Long Short-Term Memory Recurrent Neural Network has been implemented to predict the possible trajectories that passengers may travel within the airport depending on user-defined passenger profiles. The aim of this research is to improve passenger flow predictability and situational awareness to make a more efficient use of the airport, that could also positively impact communication with public and private land transport operators.

Towards Climate Resilient Freight Transport in Europe

Abstract: Climate change is related with weather extremes, which may cause damages to infrastructure used by freight transport services. Heavy rainfall may lead to flooding and damage to railway lines, roads and inland waterways. Extreme drought may lead to extremely low water levels, which prevent safe navigation by inland barges. Wet and dry periods may alternate, leaving little time to repair damages. In some Western and Middle-European countries, barges have a large share in freight transport. If a main waterway is out of service, then alternatives are called for. Volume- and price-wise, trucking is not a viable alternative. Could railways be that alternative? The paper was written after the unusually long dry summer period in Europe in 2022. It deals with the question: If the Rhine, a major European waterway becomes locally inaccessible, could railways (temporarily) play a larger role in freight transport? It is a continuation of our earlier research. It contains a case study, the data of which was fed into a simulation model. The model deals with technical details like service specification route length, energy consumption and emissions. The study points to interesting rail services to keep Europe’s freight on the move. Their realization may be complex especially in terms of logistics and infrastructure, but is there an alternative?

Existing barriers and suggested solutions for dealing with air passengers with specific access requirements: A systematic literature review

This paper reviews the existing literature concerned with air passengers with specific access requirements, often referred as passengers with disabilities (PwDs) or passengers with reduced mobility (PRMs). While accessibility in air transport is an emerging field of research, the literature lacks a more in-depth understanding of the barriers that air passengers face, which can guide future research and help practitioners in improving the services to this passenger segment. To this end, we conducted a systematic review of 50 peer-reviewed articles to explore how these challenges have been addressed in existing literature. The analysis expanded upon the established primary barrier categories (architectural, transport, communication and information, attitudinal, and technological). Within these categories, novel sub-groups of barriers were identified and proposed. The analysis further revealed the most suggested solutions to overcoming those barriers: i) legal obligations and standard operational procedures; ii) improving airport facilities and services; iii) digitalization of operations and services; iv) recommendations for improving cabin safety and accessibility; and v) training for airport and airline staff. This study emphasizes the importance of gaining a thorough understanding of the challenges faced by PwDs and calls for more collaborative efforts from various stakeholders to enhance the accessibility and inclusivity of air travel.

Indirect taxes and subsidies for international tourism passenger transport and conflicts with climate policies: a European case study

Extended ATM for Seamless Travel (X-TEAM D2D)

X-TEAM D2D project is focused on integrating Air Traffic Management and Urban Air Mobility into an overall multimodal transport network to address the potential increase in efficiency of the overall transportation system in the future, considering the operational domain of the urban and extended urban environment up to a regional extent and passenger-centric perspective. This paper presents the analysis of the Door to Airport trajectory of business passengers until 2035. The results indicate the system's expected performance in 2035 under normal and disrupted scenarios providing insight on the expected impact of future technologies.

X-TEAM D2D Project: Designing and Validating a Concept of Operations for Door-To-Door Multimodal Transport

The project X-TEAM D2D (extended ATM for door-to-door travel) has been funded by SESAR JU in the framework of the research activities devoted to the investigation of integration of Air Traffic Management (ATM) and aviation into a wider transport system able to support the implementation of the door-to-door (D2D) travel concept. The project defines a concept for the seamless integration of ATM and Air Transport into an intermodal network, including other available transportation means, such as surface and waterways, to contribute to the 4 h door-to-door connectivity targeted by the European Commission in the ACARE SRIA FlightPath 2050 goals. In particular, the project focused on the design of a concept of operations for urban and extended urban (up to regional) integrated mobility, taking into account the evolution of transportation and passengers service scenarios for the next decades, according to baseline (2025), intermediate (2035) and final target (2050) time horizons. The designed ConOps encompassed both the transportation platforms integration concepts and the innovative seamless Mobility as a Service, integrating emerging technologies, such as Urban Air Mobility (e.g., electric vertical take-off and landing vehicles) and new mobility forms (e.g., micromobility vehicles) into the intermodal traffic network, including Air Traffic Management (ATM) and Unmanned Traffic Management (UTM). The developed concept has been evaluated against existing KPAs and KPIs, implementing both qualitative and quantitative performance assessment approaches, while also considering specific performance metrics related to transport integration efficiency from the passenger point of view, being the proposed solution designed to be centered around the passenger needs. The aim of this paper is to provide a description of the activities carried out in the project and to present at high level the related outcomes.
